What is a SIM card?

It stands for Subscriber Identity Module, but you should think of it like your phone’s brain. It stores all your personal information, like phone numbers, address book and text messages. And when you want to upgrade or change phones all you do is remove the SIM from your current phone and put it in the new one.

Each SIM card has a unique serial number that needs to be activated before you can use it in a new phone, but it’s super fast and super easy.

Please use the search tool on the Bring your own Mobile Internet device page to determine the SIM card type needed for your device.
